That is to say, the height of baffle 2 in the up-down direction, and the casing 1 with the inside diameter of baffle 2 relative position between the size ratio within 0.4 to 0.9, when the height of baffle 15 in the up-down direction and the inside diameter size of casing 14 with the corresponding position of baffle 15 between the size ratio is less than 0.4, the air bubble mixed flow can only get into the dissolved water chamber through the through-hole of baffle 15, the air bubble mixed flow is less, and the air bubble mixed flow is incomplete, inhomogeneous with the mixture of water, has reduced the content of micro-nano bubble in micro-nano bubble water to the quality of micro-nano bubble water has been reduced.

When the ratio of the height of the partition plate 2 in the up-down direction to the inner diameter of the shell 14 corresponding to the partition plate 15 is larger than 0.9, the distance between the upper side of the partition plate 15 and the upper end of the shell 14 is larger, a large amount of air bubble mixed flow directly enters the dissolved water cavity from the mixing cavity from the upper end of the partition plate 15, so that the air bubble mixed flow in the main cavity is incompletely and unevenly mixed with water, the quantity of micro-nano bubbles in the micro-nano bubble water is reduced, and the quality of the micro-nano bubble water is reduced.

Therefore, the ratio of the height of the partition 15 in the vertical direction to the inner diameter of the shell 14 at the position corresponding to the partition 15 is 0.4 to 0.9, so that the mixing speed of the air bubble mixed flow and the water in the main cavity is accelerated, and the air bubble mixed flow and the water are fully mixed.

For example, the ratio between the height of the partition 15 in the up-down direction and the inner diameter dimension of the housing 14 at the position corresponding to the partition 15 may be: 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, etc.

Preferably, as shown in fig. 4, the ratio of the height of the partition 15 in the vertical direction to the inner diameter of the position of the housing 14 corresponding to the partition 15 is 0.4, so that the quality of the micro-nano bubble water is ensured, the mixing speed of the air bubble mixed flow and the water in the main cavity is increased, and the air bubble mixed flow and the water are mixed sufficiently.

When the water inlet pressure is lower than the air inlet pressure, the water inlet 12 is firstly closed by using the dissolved air tank 1, high-pressure air enters the shell 14 of the dissolved air tank 1 through the air inlet 11, water in the dissolved air tank 1 is injected into the dissolved air tank 1 from the water outlet 13 through a plurality of water inlet holes, the air enters the dissolved air tank 1, and compressed air is stopped after the dissolved air tank 1 is filled with partial or all air. Then, the water inlet 12 is opened, high-pressure water enters the gas-liquid mixing cavity 16 of the dissolved air tank 1 through the water inlet 12, in the high-pressure gas-liquid mixing cavity 16, water flow impacts to form air bubble mixed flow, the contact area of air and water is increased, the content of the air dissolved in the water is increased, finally dissolved water is formed, and the dissolved water flows into the dissolved water cavity through the partition plate 15.

Because the water hole size of the micro-nano bubble water micro-channel of the micro-nano bubble generator 41 is small, especially when the water pressure of the inlet water is small, the water outlet amount is small, and the normal water demand of the user is difficult to meet. Therefore, the micro-nano bubble generator 41 may be provided with a gap water passing channel besides the micro-nano bubble water micro-channel, when the water pressure of the inlet water is low, the gap water passing channel may be turned on to increase the water output of the micro-nano bubble generator 41, and when the water pressure of the inlet water is high, the gap water passing channel may be turned off to allow the micro-nano bubble water to flow out of the micro-nano bubble water micro-channel of the micro-nano bubble generator 41.

When the micro-nano bubble water device 100 is used, after a user opens the water outlet valve 61, water flow sends a water flow signal to the controller 3 through the water flow sensor 71, when the liquid level sensor in the dissolved air tank 1 detects that the water level in the gas-liquid mixing cavity 16 is higher than a preset set position, the water flow signal is sent to the controller 3, the controller 3 controls the inflator 52 to be started, the inflator 52 pumps air with the pressure in the range of 0.1MPa to 1.2MPa into the gas-liquid mixing cavity 16, the water flow is mixed with the air under the action of water pressure, the air is dissolved in the water, after the air in the gas-liquid mixing cavity 16 is gradually dissolved in the water, the air is gradually reduced, the inflator 52 carries out continuous or intermittent inflation, and the air in the dissolved air tank 1 is supplemented, so that micro-nano bubble water is continuously generated. When the micro-nano bubble water flows out of the water outlet piece 4, the micro-nano bubble water passes through the micro-nano bubble generator 41 in the water outlet piece 4, and therefore the micro-nano bubble water is generated.
